Description
Technical field
The present invention, about a kind of acryl optical cement constituent, refers to that one can effectively control product setting rate especially, and can effectively avoid product to go bad the optical cement of use transparent acrylic monomer of jaundice.
Background technology
In the information age now, the mankind grow with each passing day for the dependency of electronic product, the electronic products such as notebook computer, mobil phone, personal digital assistant device (personal digital assistant, PDA), digital walkman have become application tool indispensable in modern's life and work all.Above-mentioned electronic product, all except having an indicating meter, also must provide an operator-machine-interface simultaneously, and the built-in system of transmission user and electronic product is linked up.
Along with user is to the requirement of the display quality of indicating meter, convenience and friendly degree, display panel (display panel) arranges contact panel (touch panel), replace the conventional input devices such as button or mouse with contact panel, provide user and utilize finger or pointer etc. to carry out the approach of interactive input operation.
Generally speaking, touch control display panel is made up of contact panel and liquid crystal panel, most engagement means is based on gummed, that is after the prospective region of a slice plate is wherein coated with an optical cement (OCA), again another sheet plate correspondence is fitted with this plate being coated with optical cement, utilize UV-light that this optical cement is solidified subsequently, to complete the preparation of this touch control display panel.
Above-mentioned use optical cement forms the form of construction work of two plate laminatings, before optical cement not yet hardens, the trip edge between two plates all easily produces the glue that overflows, and must wiping in real time remove, in wiping process, optical cement still can continue to overflow, difficult treatment and quite consuming time; Especially, if optical cement is excessive and do not remove in real time, by more difficult removing after its sclerosis.Therefore, industry also uses one to make without base material by optics acryl glue, then at upper and lower bottom, the OCA optical adhesive tape of one deck release film of respectively fitting again, in order to form the comprehensive laminating of touch control screen, replace the mode of conventional mobile phone screen welt frame, effectively replace the gas cloud that must have because of welt frame, reach the effect improving screen contrast with physical property material.
In principle, similar OCA optical adhesive tape, in time making, after the acryl monomer be pre-mixed and film forming material mix and blend, then coordinates the irradiation of UV light and hardened forming; Only, when actual job, the acryl monomer that it is pre-mixed likely because store improper or the storage time is long, and rottenly even affects the follow-up light-struck setting rate of UV that accepts; Therefore, how to develop one and can effectively control product setting rate, and can effectively avoid product go bad jaundice curable composition, for industrial community and academia desire most ardently the problem of solution.
